Objective To explore the optimal technique for digestive tract reconstruction of proximal gastrectomy. Methods Fifty-nine patients who underwent proximal subtotal gastrectomy during June 2004 and January 2007 were analyzed retrospectively. All patients were divided into 2 groups according to the styles of reconstruction: one group with gastroesophagostomy (GE group) and the other with accommodation double tract digestive reconstruction of jejunal interposition (GIE group). The reconstruction of GIE group was to interposite a continuous 35 cm jejunum between the gastric stump and the oesophagus, which detail had been reported in our previous literature. The quality of life in 2 groups were evaluated and compared. Results No patient died and there was no anastomotic leakage, dumping syndrome and moderate or severe anemia occurred during perioperative period. There was no significant difference of the following indexes of nutrition between 2 groups 1 month and 6 months after operation: the value of weight, RBC, Hb, Alb, PNI and the indexes versus the preoperative ones (Pgt;0.05), for the exception of the indexes of RBC (P=0.006), Hb (P=0.001) in 1 month after operation versus the preoperative ones. The abdominal and the reflux esophagitis symptoms in GIE group were milder than those in GE group (Plt;0.001). The Visick scoring: most of the GIE group were gradeⅡ (74.2%), and grade Ⅲ (64.3%) in the GE group. There was no delay of the first time of adjuvant chemotherapy in GIE group (Pgt;0.05), and the surgical time was (0.35±0.13) h more than that of GE group (P=0.01). Conclusion The accommodation double tract digestive reconstruction of jejunal interposition for proximal subtotal gastrectomy may be safe and feasible by decreasing residual cancer cells and improving the quality of life of patients with proximal gastric carcinoma who underwent such surgical procedure.
